Abstract

An alignment device for use with machinery in accurately aligning a machinery device train having a first and a second assembly. The alignment device comprises a central plate that has a curved surface and an opposing flat face. A disc with a curved surface is slideably engaged with the curved surface of the plate and a disc with a flat surface is slideably engaged with the flat surface of the plate. The alignment device is interposed between first and a second assemblies and preload compressive force is applied to the alignment device. Selective sliding movement of the two discs with respect to the plate, independently aligns the lateral and angular relationship of the upper and lower assemblies without the need to unload the alignment device. Maintaining the preload on the alignment device after alignment is accomplished prevents the introduction of alignment errors.
